Specification of Letters Patent.

- 7 Application filed July 15,

To allwhom it may concern: 7

Be it known that LMATTHEW II. FARNns, a citizen of the United States,residing at Logan, in the county of Cache and State of Utah, haveinvented certain new and useful Improvements in Stoves, of which thefollowing is a specification.

My invention relates to stoves, and has for its object to flprovide astove wherein deflectors or ba es are secured and operated to direct theheat currents radially outward to cause a more perfect combustion, andto direct the heat currents against the sides of the stove whereby moreheat is generated and radiated than has been done and thereby effect asaving of fuel.

These objects I accomplish with the stove illustrated in theaccompanying drawing in which similar letters and numerals of referenceindicate like parts throughout the several views, and as described inthe specification forming a part of this application and pointed out inthe appended claims.

In the drawing in which I have shown a substantial embodiment of myinvention, Figure 1 is an elevation of a heating stove, with parts cutaway to show the baffle elements. Fig. 2 is a plan view of the stove.Fig. 3 is an elevation of the lower baflie element.

I, am aware that stoves have been constructed wherein deflectors havebeen provided to direct the heat units, but so far as known to me nonehave used concave baffle plates to provide a concavity above the firewithin which a more perfect combustion of the fuel may be effected, andwhich baffle plates are so mounted that the lower one will, in additionto providing the conoavity as above set out, also direct the heat unitsradially outward thereby effecting a better combustion, but will tend todirect said heat units against the sides of the stove, and with anotherbafiie plate or element so positioned that the heat units will be keptin general direction against the sides of the stove, and will alsoprovide another combustion chamber near the top of the stove withinwhich all of the unburned carbon will be consumed and the heat currentskept against the side walls of the stove.

The present invention consists of the usual side walls A having a fuelfeeding door B, a fire box C, an ash box D and a pipe for smoke egressE. A frusto-conically shaped baffle 1 is suspended from a rod 2 by thechain 3 PatentedNoiEZ, 1921. Serial No. 484,922. I

and said rod 2 is journaled for rotation in the sidewalls of the'stove,in order that when said rod 2 isrotated the said baffle-1 may be raisedfor building a fire and for supplying fresh fuel as desired, the chain 3being wound on the rod. One end portion of said rod 2 is shaped to beengaged by a crank for rotating said rod to raise and lower the baflieelement 1. The lip or edge of said baflie 1 has a portion 4 bent orrolled outwardly and upwardly to allow a portion of the heat units toescape thereunder whereby the tendency of the heat currents to flowtoward the flue or pipe E is neutralized. The under side of said bafiie1 is concave or hollowed out to form a combustion chamber and saidbaffle may be given the form of a frustum of a cone, as shown, or if thestove is rectangular in cross section, the baffle will then be givenmore the shape of the frustum of a pyramid. Near the top of the stoveanother bafiie 5 is secured with the concavity upwardly placed and theapex downward, and this baffle is to continue the directing of the heatunits induced by the lower bafiie 1 toward the walls of the stove.

As will be obvious my invention may be used in constructing furnaces orother stoves where the form of thebaffies will be modified as desired.

Inoperating the stove, the baiile 1 is raised by rotating the said rod 2and when the initial fire has been started and the re uired amount offuel has been placed within the fire box C the chain 3 is unwound andthe baflie is allowed to rest on the fuel, the fire box being alwayswider thanthe battle 1 to provide a flame passage between the fire boxand the bafiie. The combustion chamber provided by the concavity of saidbaifles insures a more perfect combustion of the fuel, and the directingof the heat currents effects a great saving of fuel for the amount ofheat radiated.

Having thus described my invention I desire to secure by Letters Patentand claim 1. In a stove the combination with the side walls thereof, ofan inverted cone secured near the top of said stove; a frusto-conicallyshaped baffle vertically movable in said stove, and having outwardly andupwardly flared portion in the base edge thereof; and means to move saidbaflie vertically in said stove.

2. A stove comprising a battle suspended and vertically movable therein;a portion of the edge of said bafile curved upwardly and outwardly toform a flame conduit; a

combustion chamber formed by the con-' cavity under said baffie; meansto raise and lower said baffle; and an inverted cone secured near thetop of said stove to 'coact With the said baflie in keeping the heatunits adjacent the Walls of said stove. H 3. A stove comprising a bafllesuspended and vertically movable therein; a portion of the edge of saidbafiie curved upwardly and outwardly to form a flame conduit; acombustion chamber formed by the concavity 7 under said bafiie; a rodmounted in the Wall 15 the heat units adjacent the Walls of said 20 Vstove.

In testimony whereof I have afli ied my signature.
